Recently, German scientists studied the relationship between electromagnetic fields (EMF) and tinnitus in a 2009 study. Tinnitus occurrence and tinnitus severity were assessed by questionnaires in 89 electromagnetic hypersensitive and 107 controls matched for age, gender, living surroundings, and workplace. Tinnitus was significantly more frequent in the electromagnetic hypersensitive group (50.72 percent vs. 17.5 percent), whereas tinnitus duration and severity did not differ between groups.
The researchers concluded, "Tinnitus is associated with subjective electromagnetic hypersensitivity. An individual vulnerability probably due to an over-activated cortical distress network seems to be responsible for both. Hence, therapeutic efforts should focus on treatment strategies (e.g. cognitive behavioral therapy) aiming at normalizing this dysfunctional distress network.
The microwave auditory effect, also known as the microwave hearing effect, consists of audible clicks (or, with modulation, whole words) induced by pulsed/modulated microwave frequencies. The sounds are generated directly inside the human head without the need of any receiving electronic device. The effect was first reported by persons working in the vicinity of radar transponders during World War II. These induced sounds are not audible to other people nearby.
Many people improve when the offending RF source is removed from their environment.
